Welcome to the
Turing
Xserve Cluster

Welcome to the Turing Cluster. Located in the Digital Computer Laboratory, the Turing Cluster consists of 768 Apple Xserves, each with two 2 GHz G5 processors and 4 GB of RAM, for a total of 1536 processors. The primary network connecting the cluster machines is a high-bandwidth, low-latency Myrinet network from Myricom. In addition, all machines in the cluster are also connected by a 100 Mbs switched, full-duplex Ethernet using switches from Cisco Systems, and there is a 1 Gbs link between the front-end array and the primary Cisco switch. The operating system for the Turing Cluster is Mac OS X Server, currently version 10.3. The cluster can be accessed only via secure shell (ssh or slogin) to the front-end array, turing.cse.uiuc.edu.

The Turing Cluster was created using Apple Computer technology with financial contributions from

Beckman Institute College of Engineering Computational Science and Engineering Department of Computer Science Department of Electrical and Computer Engineering Materials Computation Center Materials Research Laboratory Office of the Vice Chancellor for Research

The Turing Cluster is operated by Computational Science and Engineering, with system administration provided by the Workstation Services Group of CITES. Most general questions and requests for help should be addressed to turing-help@cse.uiuc.edu. If necessary, the system administrator can be contacted by email at manager@turing.cse.uiuc.edu.

The Turing Cluster is available on a limited basis for use in research or class projects by UIUC students, faculty, and staff affiliated with the Computational Science and Engineering Program or one of the other sponsoring units. Requests for accounts should be addressed to turing-accounts@cse.uiuc.edu and are subject to administrative approval by CSE. Sharing of accounts is forbidden — each user MUST have his or her own individual account and password. The cluster is shared by many users, so users should be respectful of each other and not monopolize resources or engage in other antisocial behavior. Violation of any of these policies may result in account termination as well as potential disciplinary action by the university.
